Application filed November 22, 1901. Serial No. 83,302.

To all whom it may concern:

Be itknown that I, SAMUEL Conn, a citi-- zen of the United States, andresiding in the borough of Manhattan, city, county, and St ate of NewYork, have invented certain new and useful Improvements in Machines forGathering and Sewing the Heads of Mantles, of which the following is aspecification. My invention relates'to machines for gathering and sewingthe heads of mantles and has for its object to produce a machine whichwill gather and sew mantle-heads, but it is also adapted to gather andsew the mouths of bags and other tubular structures.

In U. S. Letters Patent No. 678,542, granted to me on July 16th, 1901, Ihave shown a machine for gathering the heads of mantles;

My present invention in some of its constructive details may be said tobe an improvement u )on this general type of machine.

, In the accompanying drawings I have shown a machine embodying one formof my invention. But it'is to be understood that this drawing isillustrative merely and is not to be taken as representing all forms ofmachine in which my invention maybe em bodied.

In the drawing, Figure I is a front view partly broken away showing byway of illustration a machine in which my invention is embodied; Fig. IIis a plan view of the machine showing one of the sets of jaws andoperatin mechanism in horizontal section; Fig. I I is a side view of themachine; Fig. IV is a section on line 4-4 of Fig. II; Fig. V is a detailview ofthe mechanism for discharging orthrowing out the mantles afterthey have been sewed; Fig. VI is a detail view of the device foreffecting the needle motion; Fig. VII is a broken away detail view ofthe needle bar of the machine; Fig. VIII is a longitudinal sectionalview of the clutch mechanism; Fig. IX is a transverse sectional viewthereof Fig; X is a detail view of the mechanism for moving the gripperbar for gripping the threads; Fig. XI is a side view of one member ofthe sets of jaws; Fig. XII is a side or face viewof one member oltheother set of jaws; Fig. XIII is a sectional view taken on line 1313 ofFig. X I; Figs. XIV, XV, XVI, XVII show the p itions of the parts in thevarious stages of the sewing operation; and Fig? XVIII shows in diagramthe compileted product of the machine. Fi XIX, i X, and XXI are planviews of the ower intermediate and upper transfer slides,.re'spectivcly.

The main objects of m produce a machine in w ich a number of mantles maybe sewed at once and in which the mantle after it is sewed may bereadily removed from the jaws.

By referring to my U. S. Letters Patent, above mentioned it will beobserved that I have shown therein means for bending the mantle materialand for. passing a thread through the material while so bent orcorrugated. the same set of principles an before pro ceeding to describethe detailed construction of the machine I will set forth the generalmode of operation.

Referring for the present to Figs. XIV and XVIII inclusive d and I)represent the movable jaws having elevations and depressions thereinafter the manner of a cor-. rugation. movable jaws of simi ar structure.6 represents the mantle which is adapted to be bent or corrugated whenthe jaws co-a'ct with each other as shown in Figs. XV and XVII. Theteeth f of the jaws c and d, which jaws together constitute a centertoothed member having corrugations on opposite sides thereof, areslotted as shown at g for the passage of the needle, and in ad-' ditionare provided with suitable springs In Fig. XI I have shown in ;face viewone of the outer jaws. This outer jaw ahas invention are to i My presentmachine 0 crates upon c and (I re resent another pair of a slotttherein, but as these jaws move.

away from the mantle and do not carr the mantle, it is not essentialthat they s ould be provided withsprings it. these springs h is to aidthe operator in removing the mantle from the toothed center memberconstituted by the jaws c-d. I have found in operating the machineforming' the subject-matter of my patentabov'e mentioned, that ine.orie'nced operators sometimes have diflicut mantle from the toothe,center member 7c /shown therein, as the threadis liable to in removingthe The office of I n1 mi:

as the machine shown in and forming the subject matter of my saidpatent, so that the specific operation thereof need not be describedhere, except to state that the center member is made in two parts whichare movable with respect to each other.

In Fig. XIV the jaws are shown separated. In Fig. XV they are shown asclamping the mantle. In Fig. XVII the parts are shown in the positionwhich they assume while the thread 7' is being drawn through the mantle;and in Fig, XVIII the completed open-mouthed structure is shown.

Having given briefly the general object and purpose of the machine Iwill now proceed to describe the detailed construction thereof.

The frame-work of the machine is indicated by the letter I. Thisframe-Work supports all the operating parts and is provided with a frontguide-bar Z and a rear guide-bar m. The jaws aand b are carried upon theslides whichoperate on these guide-bars. The jaw a is carried upon theslide a. The jaws d and c are carried stationarily upon the frame-workof the machine, that is to say, the said jaws are stationary in positionon the machine, but each jaw is mounted upon a spring arm; the jaw'dbeing carried upon a spring arm cl, and the jaw a being carried upon aspring arm 0 These springs hold the jaws in position, back to back, sothat they constitute a center member toothed on opposite sides. Thesejaws c and d are adapted to be spread apart by a slide or spreadingmeans 0 so that they will assume the position shown in FigsI XV and XVIIatv the proper time as will be explained. The jaw a is carried,

upon a spring arm a carried upon a slide 0. The jaw b is carried upon aflexible arm 0 carried upon-a slide 0 The jaws a and b are adapted to bemoved inward towards the faces of the jaws c(Z, after the said jaws havebeen positioned for operation. This inward movement is accomplished bythe beveled face of the slide 0 acting upon the jaw l), and the beveledface of the slide 0 acting upon the jaw a as will be explained.

There are several groups or sets of jaws. in the present instance I haveshown three, A, B and (.9 These sets of jaws are all similar andsimilarly operated. The movements of the various parts of the machineare effected and initiated by means of a suitable main cam shaft 1;,having thereon a set of cams for bringing about the various operations.The movements of the slides c and c of the various 7 sets is effected bymeans of a rod 6 nect'ed to suitable arms e which are at e in theframe-work of the machlne and are provided with bowls e which enter slotThis rod e passes rigidly through each of the slides c-c of the'severalsets and slides in the slots of the slides 0 c and c of the severalsets. Suitable arms e e are ivoted at e on the frame-work of the mac ineand arev connected to the rod e These arms e are provided with bowls ewhich operate in a cam slot e of the cams e As the cams e rotate theupper ends of the arms 6 will be swung forward, thereby moving the outerset of jaws ab forward to position them for cois not shown in thedrawings, but it will be understood that the slides c and 0 move for-Ward until the jaws ab are 0 posite the corrugated jaw-faces cd. It wilbe underoperation with the center toothed member 'or double set of jawsc(Z. This positioning stood that the jaws after they are ositioned foraction are set into action as to lows:

The slide or separating means 0 enters'between the two ortions 0-11 ofthe center corrugated mem er and spreads them a art, and the slides c"cpress the jaws a inward to 006 erate with the corrugated jaw portions cdThis movement will be obvious from an inspection of Figs. XIV and XV,wherein the jaws are shown in their different positions. The slides 0 c"and 0 receive their movement as follows:

The rod (2 is rigidly secured to the slides 0 0, 0 of each set of jaws.This rod is conpivoted e" inathze cams 6 The cam e is so timed withrespect to the cam e that the slides e, e, e are caused to move forwardafter the jaws a-b have been positioned for action. The needle motionshown in the present machine is as follows: The needles 0 are arrangedin pairs upon a needle-bar 0. The needle bar 0 rises and falls insuitable guides 0 being actuated by the links 0" pivoted thereto and toarms 0 (see Figs. IV and VI), which arms are pivoted at 0" and arepivotally connected bythe link 0 toan arm 0 pivoted at 0 and providedwith a bowl 0 adapted to cooperate with cams e on the main cam shaft 6.A rising and falling motion is thus imparted to the needles. Theneedle-bar in its movement is adapted to contact with the cross or stopbarf carried upon suitable guides f9, surrounded by spiral springs fThese cross-bars are adapted to receive the impact of the needle bar.

Suitable guides 61 and d are provided for the double purpose of aidingin guiding the needle if necessary and guiding the mouth or head of themantle onto the oppositely corrugated center-member. 1

Having described the operation of the jaws and the needle motion, I willnontiproceed to describe the operation of the threader socalled. By athreader I mean to'include an automatic means whereby the thread IS isofit I slides, one above the other.

.amsed to be passed through the needle eyes. I shown in Figs. XX andXXI. When these In the present instance I for passing the ends of thethread in opposite directions through the eyes of the pairs of needles.In the machine shown in the accompanying drawing I em loy thread loopsinstead of a continuous ength of thread. This thread loop 7' is clearlshown in Figs. XV, XVII and XVIII. xtendin across the machine are barsss. These ars are adapted, to support the thread loops, the bights ofthe loops being thrown across said bars. A bar a is adapted 'to lie inthe space between the. bars .es in order to rip the loops. This bar 9 iscarried u on t we arms a pivoted at 8 to the frame 0 the machine andhaving connected thereto a link 8. This link I is shown in the presentinstance as slotted tosurround the shaft e and is provided with a bowl 8adapted to cooperate with a cam s on the cam shaft e? The parts justdescribed to ether with a spring not shown constitute t e actuatingmeans for the bars 8 to cause it to ascend or descend to gri the bightsof the threads 7'.

The free ends 7" and j of the threads are laid in hooks v-'v carriedrespectively upon slides v.'v These slides 'v v extend transversel ofthe machine over the jaws dare-a apted to receive a reciprocatingmovement. This reciprocating movement maybe variously imparted to thesaid slides. In the present instance I have shown three The lowermostof. these slides a is provided with straight extending in the directionof movement 0f the slides which actuate the crimping jaws. The slidesthemselves are carried u n slides v"'v at each end of the machine, w 'chslides are provided with pms a passing through all of theslots of thelateral or transverse slides U2U31)4.

The slides v'v -'v are slotted lon itudinall with slots '0 so that thesaid sli es are worked u n the said pins. The slides 12 0.

' are move back and. forth in the machine by links 1) pivotallyconnected to the said slides at one end and on the rock shaft or pivotalThese arms Q) are operated by cams 12" so that as the main cam shaft 6revolves the slides carrying the threader books will be moved bodil backand forth in the machine to position t e said threader. for action whenthe needles have passed through the fabric andtare in'position to bethreaded.

The lowest slide o carries no hooks and is provided with transverseslots v. The intermediate and upper slides o and o respectively; whichvcarry the hooks o and a, respectively, are provided with the slots u ano", respectively. These slots run fora portion of-their lengthtransversely of the slides and turn-at an angle of 45 near one ave shownmeans ,ments of the plates v and c respectively.

When these pins strikethe parts of these slot-s which lie at an angle ofabout 45 to the transverse portion, these plates are. shifted tocorrespond to the change in direction of the slots which movement isallowed by the longitudinal slots v above described.

The motion imparted by the cams 11" which move the slides v"v toposition the threader for action, is so timed with respect to the motionimparted by the cams e that no lateral motion of the slides v w on eachother will take place during the positioning movement, but when thepositioning has been effected forward movement of the slides c"-c willcause motion to be imparted to the.

lates or slides v-'-v'- in order to cause the ooks 12- -12 to approacheach other'and recede from each other while they are positioned foroperation. The detailed operation of the contruction will be carefullytraced hereinafter.

In order to e'ect the finished mantles from the machine provide asuitable roller 00 which is journaled on the arms a: carried by theframe and is provided with a pinion x meshing .with a gear w hung upon asuitable stud on the arm a.

A ratchet w is rigidly secured to the gear a and is adapted to receivemotion from a pawl 20'' carried by a swinging arm a which is pivotallyconnected by a link as with an arm a pivoted at as working in a cam x onthe main cam shaft e (see FigrV). At themoment when the movable jaws andtheir operating'slides are retracted the operating portion of the cam asrotates the roller .7; rearwardly throwing the mantles out of themachine. A suitable presser roller 2:" is carried upon a yoke w ivotcdat :r on the frame of the machine wit '1 a spring as to hold it up toits work.

In Figs. VIII and IX I have shown a suitable clutch for effecting theactuation of the dcvicef This clutch is so arranged that when it isthrown into action it will cause the. shaft e to make one-half arevolution. Mounted on the frame-work of the machine is a sleeve orbushing 2 which is adapted to rotate freely with the shaft e which isjourna jed therein. This bushing is provided with a bolt or clutchmember 2 which is impelled forward by a spring 2 and is adapted tocontact with pins .2 on the hub z of the driving pulley 2". The

machine may be operated either by hand or by ower. I have shown means,to wit, the pul ey 2 whereby power may be applied to the machine.

5 The bolt or tooth z is provided with a pin 2 which is adapted tocooperate with a pair of arms z -2 These arms 2 -2 are pivotedrespectively at 2 -z and are geared with each other as by means ofsegment 1() gears 2 z"-. A connection 2 may be made with a treadle orother means whereby the clutch may be thrown into action.

The arms zi -2 are provided with cam faces 22 with which the pin 2cooper- 15 ates.

The mode of 0 eration of the clutch is as follows: When t e pin is inthe position shown in Figs. VIII and IX on an elevated part of the camface of one of the arms Z14Z15 the teeth 2 is held back against thepressure of its spring 2 and the ulley 2 is free to revolve. hen thetrea le is pressed down thereby through the connect-ion 2 swinging thearms z-z apart, the pin 2 being no longer held by the arm 2, the tooth 2moves forward into the path of one of the pins 2 on the hub '2 of thepulley 2 As the pulley 2 is loose upon the shaft e and the sleeve 2 isfast thereon the shaft will thus be coupled up for movement; but as thesleeve 2 rotates the pin 2 will run upon the cam 2 and when it reachesthe highest point of the cam the tooth 2 will be withdrawn and thepulley 2" will thus run freely.

The detailed operation of the machine is as follows: The mantles arefirst placed over the jaws cd of the crimpers which together constitutethe center member of the crimping device and over the rounded end guides40 (1 a roll 00 firmly gripping the mantles. The

mantles when in the condition in which they are sewed are fla ttenedtubes. These flattened tubes pass between the rollers m:r;

as the jaws are substantially vertical, they are substantially at'rightangles to the axis of the rollers. In order therefore that the flattenedtubes may properly engage the aws it is necessary to' impart thereto aquarter twist. Thereupon the movable side jaws ad Vance into position,the threading mechan- .ism being also ositioned for operation. Theseparator for t e inside movable jaws of each gang comes forward and atthe same time the compressors for the outside movable jaws for eachgang-come forward. The mantles are thus firmly gripped and the threadersare positioned. The needles now pass through the fabric and passing intothe paths of the threader hooks remain stationary for a short so spaceoftime, the machine havin completed a half revolution and the knockoutclutch having operated "to stop the machine. Thereupon the operator laysthe loops of the thread j in the machine, the ends of the loops lying 5acres the threader hooks v'v and the loops of the threader hooks lyingacross the bars hFurther rotation of-the machine will cause t e gri erbars to descen i in the loops of l he thread so as to l dl th threadsinplace while the ends are being Z'q drawn through the eyes of then'eedles. The slides c v now operate to move the threader hooks from theositions shown in Fig. XV to the position s own in Fig; XVI drawingthethreads. through the eyes of the needles and after the threader booksI have cleared the needles reeede as shown in Fig. XVII drawing thethread through the fabric; at the same time the gripper bar 8 ascends sothat the needles traw so the loops up to the fabric all as clearly?"shown in Big. XVIII which. illustrates the finished product. Theoperations are now reversed, the arts assume the' osi I tions shown inFig. XIV, the s rings op-gg; erate to throw the fabric out o thecorrugations of the center member cd and the ratchet gear is thrown intoaction to. discharge the mantles from the machine. The Shining stringsmay now be gathered up,

which may be done by hand or by machine and the mantles tied up to formafinished product.
